Vibrations and Diffusion of Atoms in Superionic Crystals and Melts
نویسندگان
چکیده
Recent computer simulation studies contain sufficient information about the atomic disorder and motion to allow a calctlation of the dynamical response of superionic crystals and melts which may be compared with measurements of inelastic neutron scattering and Raman scattering. The high frequency part of this response is essentially that of anharmonic vibrations in a disorderd lattice. The low frequency part results from correlated jump diffision of the atoms.

Optimization of A Thermal Coupled Flow Problem of Semiconductor Melts
In this paper we describe the formal Lagrange-technique to optimize the production process of solid state crystals from a mixture crystal melt. After the construction of the adjoint equation system of the Boussinesq equation of the crystal melt the forward and backward problems (KKT-system) are discretized by a conservative finite volume method.
متن کاملSuperionic conduction in β-eucryptite: inelastic neutron scattering and computational studies.
β-Eucryptite (LiAlSiO4) is known to show super-ionic conductivity above 700 K. We performed inelastic neutron scattering measurements in β-eucryptite over 300-900 K and calculated the phonon spectrum using classical molecular dynamics (MD) simulations. The MD simulations were used to interpret the inelastic neutron spectra at high temperatures. The calculated diffusion coefficient for Li showed...
متن کاملSYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]
The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
متن کاملتحلیل ریز ساختی بلورهای کوارتز در آندالوزیت-کردیریت شیست با استفاده از پراش پراکندگی الکترونی
The present study investigates the shape preferred orientation (SPO) and crystal preferred orientation (CPO) of quartz crystals using electron backscatter diffraction (EBSD) in andalusite-cordierite schist from the Ythan Valley, Aberdeenshire, in the Scottish Dalradian block. Quartz crystals in the matrix and andalusite pophyroblasts have inequant to slightly equant shapes. Quartz crystals show...
متن کاملIon Hopping and Constrained Li Diffusion Pathways in the Superionic State of Antifluorite Li2O
Li2O belongs to the family of antifluorites that show superionic behavior at high temperatures. While some of the superionic characteristics of Li2O are well-known, the mechanistic details of ionic conduction processes are somewhat nebulous. In this work, we first establish an onset of superionic conduction that is emblematic of a gradual disordering process among the Li ions at a characteristi...
